UNITED STATES PATENT fOFFIC EQ HENRY SIMS, OF ERIE, PENNSYLVANIA.

OIL-FILTER.

SPECIFICATION formingpart of Letters Patent No. 694,4-34, dated March 4, 1902.

Application filed May 31,1901.

To all whom it may concern.-

Be it known that I, HENRY SIMS, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Oil-Filters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in oil-filters, and has for its object the construction of an oil-filter in such a manner that all. of the parts thereof are readily removable, so that it can be easily cleaned, as well as other advantageous features of construction and operation, all of which arev hereinafter set forth and described, and illustrated in the accompanying drawings, in which 7 Figure 1 is a top or plan View of my improved oil-filter with the cover removed therefrom. Fig. 2 is avertical section of the same on the line a: or in Fig. 1., Fig.v 3 is another view of asection of the same in elevation with a part of the side thereof broken away.

In these drawings thus illustrating my invention, A is a can, preferably cylindrical in shape, made of sheet metal and provided with avertical wall B, which divides the same into semicyli'ndrical chambers C and D. Near the bottom of the chambers O and D, I place cocks c d for drawing off the contents of said chambers. I also secure sight-glasses E and F to the chambers O and D, so that the height of the fluid therein may be observed. In the chamber D, I also place a steam-coil d, by means whereof the fluid therein may be heated to a temperature suitable for successfully operating the filter. The coil d is preferably placed along the side of the division-WallB, so as not to interfere with the removal of the mechanism hereinafter described as operating in the chamber D. r

In the upper part 'of the chamber D there is a supplementary chamber or receiving-tank II. -From the bottom of the tankH a pipe G extends down to near the bottom of the chamber D, where it is provided with a perforated cone-shaped base G, which base G and pipe Serial No. 62,550. (No model.)

G serve to support the tank H, the whole being adapted to be lifted out of the chamber D when desired.

In the lower part of the .tank H, I place a line wire screen It, upon which I preferably place one or more layers of felt or other suitable porous material, which operates to strain oil placed in the tank I-I before it passes down 'thereof, I secure a fine wire screen j, upon which I place one or more layers of felt or other porous material K, adapted to strain the oil-tlowing into the pan Jfrom the pipeI before it passes down into the chamber 0 below the-pan J, from which it can be drawn off by means of the cock 0.

In operation the chamber D is filled with Water up nearly to the outlet-pipe I. Then if oil is placed in. the tank II the difference in the height of the tank II and the water-level causes the oil 'to'pass down through the straining materialh' and the pipe G and out through .D until it rises, high enough to flow through the outlet-pipe I into the pan J, Where it passes through the straining material K and down into the storage-chamber O. In order to expedite the washing of the oil as it passes up through the water in the chamber D, steam can be applied to the coils d, so'as to heat the watertherein to anydesired temperature. It will be observed that the construction of my deviceissuch that the tank II and its appurtenant parts can at any time'be lifted out of the chamber D, and by unscrewing the outlet-pipe I'thepan J can also be lifted out of the chamberO, thus enabling all of the parts of the device to be speedily and effectually cleansed when desired.

Having thus described my invention, so as to enable others to construct and use the same, what I claim as new, and desire to secure by Letters Patent of the United States, is-

The combination in an oil-filler, of a tank A, a vertical Wall 13 therein dividing the tank into chambers C and D, a receiving-tank H, and a pipe G extending downward therefrom in the chamber D, terminating in a conical perforated base G on said pipe,and resting upon the bottom of the chamber D, a heating-coil d in one side of the chamber D, a removable outlet-pipe I in the Wall E below
